This invention is directed-to animprovement in calendars, andparticularly to the provision of means whereby the calendar, "whensuspended from'the usual single 'support, may be ad usted to hang 1n atruen'ormal relation'from the supportirrespective making up thGbOOkcalendar are equal on' each side of the center vertical line of theofthefshiftingby gravity incident to the -adjustment' ofthecalendar*indicating leaves as they are turned from timeto timein-providing for properdate indications.

The invention is more particularlyconcerned with what may be termed thebook type of calendar'such, for example; as de scribed in connectionwith an application filed by me under date ot February -16,-1)31,Serial#516,133, wherein the calendar proper is made up in book form andopenedfor leaves from one side of the normal center of gravity ofthe calendartothe other side. Quite obviously, when the number of leaves calendar,then the weight on the opposite sides of such center vertical line isequal,but

' it is equally-apparent that if, in arranging the leaves of the bookc-alendarto show the successive date, the number of leaves'ac'cumulatingon one side of the vertical central hne of the calendar is greater thanthe number ofleaves onthe other side of su'chver! tical central line,there is a shifting of thecenter'of gravity'oi' the calendarto one sideor-the other oftheeen'tral' vertical line, andtion,therefore, isjahangiflg mea s; for, th r if provisionisnot made to take :carefofthis ica-lendanwhich is so arranged and connected with the'calendar as topermitpropershifting of the center of: gravity of the calendar in the,event such "is necessary by :a ine're bodvariation in; the shiftingoffthel fcjenter of" gravlty, the calendarWil-ljnot hang'true from] pthe usual-nail or smgle 'support by which? itis attached. tojtheiwallorotherifixture.

Of course, it is' recogn'ize'd that it=ispos--"" sible toovercome thisdisadvantage-in the use of book calendarsbysupporting the. calendar fromtwo spaced supports, astwof spaced nails or the like,b-ut ordinarilycalendars do not make provision for eoopera tion with two spacedsupports, nor is thereordinarily provided two spaced supports for thereception of the calendar. dars are usually held from a single support,

Calential requisite,"both from the standpoint-of symmetry andappearance, that thecalendar hang straighten the wall and also frol'nthepearan'ce I out ofline'position from the 'support, would present such anobjectionable a-p that itwould'be at'once discarded.

Essentially, then, book calendars of this 3 type, nodnatterhow theleaves of the book may be connected or howthe book itself may beattached to the back mounting, are designedfor hanging fro'mf'a singlesupport, and means are essential to overcome the ten- *"d'ency' of suchcalendar assuming'an inclined proper calendardate display by turningthe' position on the wall asthe weight of the leaves ofthe book calendarfavor one side orthe otherof'the vertical central-line of) suchmounting.

The calendar with which the present improvemcnt isrparticularlydesirable is the arrangement of calendar known as a book calendar,wherein the date indicating elements are in the form of leaves 1connected exposed to the eye.

in book form and removably secured in the center vertical lineof suchbook formto a backing 2 which,iaside from the calendar proper may beornamented tovany desired extent. I

The book calendar is made up of leaves 1 which, when opened fiatagainstthe surface of the backing, presentparticular calendar 'data; that is,as here illustrated, when the leaves are openedin a certainrelation,calendar data'rel-ative'to the month of January is If desired, atemporary means, such as 3, may be employed to-hold .the leavesofthebook calendar in any open relation, and if desired andaslcontemplated, certain of the leaves immediately following aparticular calendar data reading may be used for records of facts ordata in connection with the particular calendar data exposed. Then whenthese record sheets are turned in the particular direction, the .nextcalendar :data is exposed, that is, .in the present instance,-the monthof February.

It .wilLof course, be apparent, that-unless the numberof leavesof thebook calendar are on each side of'the vertical median line of said bookand backing,the weight-of the book calendar onone side is in excessofthe ,weighton theother. For example, .in the particular instance shownwhere the book calendar is open-to the month of January, the leafor.leaves at the left of-the vertical central lineof the book calendarand backing are .very muchless in number thantheleaves 2to the'right ofsuch line, and hence the calen dar, ifswung froma single support, as ispractically .the universal practice, would have atendency totilt towardthe left and thuslpresent an objectionable appearance, to saynothing ofa corresponding difficulty in easily reading the calendar data. Thistendency would continue until theleaves had .beenturned to.a positionwhere they were equal in number on both sides of the .line,

-itywhich, if free to act, would tend to an inclined position of thecalendar on the wall, and it is to avoid this objection that the presentinventionis particularly designed.

In carrying out the invention and in the preferred form illustrated inFigures 1 and 2, the hanging elementis in the form of a bar 4swinginglyor pivotally connected at 5 to the backing in the longitudinalmedian line of such backing and book calendar, with said bar of a lengthto extend above the upper edge of the backing and formed with an opening6 to cooperate with the usual nail or other element projecting from thewall or fixture to which the calendar is to be attached. The pivotal or.swinging relation at 5 between the bar l and the calendar backing is ofsuch character that the frictional engagement between the bar 4 and thebacking 2is such :as to overcome anytendency to disturb this relationthrough the weight of the backing and the book calendar carried thereby.That is to say, the hanging bar 4, if placed in any position, that is,any angular relation .to the longitudinal vertical median line of thebacking and book calendar, will remain in that position even ifsubjected to the weight of the backing and book calendar.

Assumingthat-the calendar is supported from theusual nail or likeelement and the position of the calendar leaves of the book calendarshift the specific gravity of the calendar as a whole to the right ofthe longitudinal median vertical line of the backing .and bookCIl011dl1,tl11$ would at once tilt the calendar from such hangingelement and if,

through the provisions of the present invention, the calendar, ormoreproperly the backing thereof, is shifted bodily into a vertical normalposition, the hanging bar 4 assumes an inclination .to the longitudinalmedian vertical line of the backing and book calendar ,with the resultthatthe calendar is bodily shifted to the'left of the hangingelement orsubstantially in line withjthe new center of gravity of the calendar asa. whole. As'the weight of'thebacking and book calendar isinsufiicientto overcome the frictional cooperation-between the hangingbar 4 and the backing 2, the calendar will remain in this position untilby the turning of the leaves of the book calendar, the center of gravityshifts to the other side of the longitudinal vertical median line. Thiswould immediately result .ina tilting of the calendar and again thecalendar is bodily shifted to move the'hanging bar to the Opposite sideof the'longitudi leaves of the book calendar, as will be plainly obviousfrom the above.

In Figures 3, 4 and 5, I have illustrated a slight modification of thehanging arrangement, wherein the hanger proper instead of in the shapeof a disk 7 pivotally supported at 8 on the backing 9 and extendingabove the upper edge of the backing, being formed in such extendedportion with an opening 10 for cooperation with thenail or othersupporting element. Here the function is exactly the same as vdescribedin connection with the preferred form. That is to say, the frictionalcooperation between the disk 7 and the backing at the pivotal point 8 issuificient to overcome any tendency to change the relation of the diskand backing under the weight of the calendar per se.

In this form, the operation described in connection with the preferredform is carried out to maintain the calendar in an upright straightposition on the wall. The calendar is merely bodily shifted, whicharranges the backing and calendar proper in such relation to thesupporting element engaging the opening 10 as to maintain said openingin line with the shifted center of gravity.

Of course, in shipping the calendars in bulk, any extension beyond thenormal edges of the backing are objectionable as presenting obstructionsto close packing. In the preferred form, the bar 4 may be merely turneddown below theupper edge of the backing.

In the modified form, as the hanging element is in the shape of a disk,it could not ordinarily be'caused to assume a position below the upperedge of the backing, and for this purpose such disk is made in twosections, alower section indicated at 11 and an upper section indicatedat 12, and these sections are connected by a more'or less flexible strip13 forming a hinge. Inuse, for supporting thecalendar, the sections 11and .12 are in vertical alignment, as lndicated 1n Flgure 4; Inarranging the calendar for shipment or for storage, the section lO'isturned down on the hinged strip 13 so that the entire supporting disk 11is arranged'below the upperedge of the backing 9, as illustrated inFigure 5 of the drawings. i

The essential feature of the present invention, as borne out by bothforms here illusvendar.

trated and described, is a-hanging connector forcalendars through whichthe shifting of the center ofgravity'of -the calendar as the calendardata isadjusted on such calendar may-be compensated" for by amereshifting ofthe calendar as a whole without withdrawing it from thehanging element or in any way changing the relation of the partsexceptthat incident to such shifting. An essential characteristic'of themounting is that the frictional cooperation between the mounting andcalendar proper is such as to overcome the weight of the cylinder properunder all conditions so that when shifted to compensate for a shift inthe center of gravity of the calendar proper, the calendar remains inits shifted position independently of the weight. being a bar, asat 4 inthe preferred form, is 1 I claim 1. A calendar of the type wherein thecenter of gravity is shifted relative to the longitudinal median line ofthe calendar in the adjustment of the date data, including means forhanging the calendar, said means being shiftable in accordance with theshift in the center of gravity and having a frictional cooperation withthe calendar normally sufiicient to overcome the weight of the calendar.

2. A calendar of the type in which the center of gravity shifts in theadjustment of the date data, including a hanger having pivotal andfrictional connection with the calendar and .formed with means to engagea hanging element, the frictional cooperation between the hanger andcalendar being suflicient to overcome the weight of the calendar, thehanger being otherwise free to shift the point of connection betweenthe. hanger and calendar to one side or the other of the hangingelement.
